How can i get the req.body before bodyparser to implement dynamic folder uploading? Should I just use the event "end"? 

app.use('/upload', function (req, res, next) {
  // imageVersions are taken from upload.configure()
  upload.fileHandler({
    uploadDir: function () {
      return __dirname + '/public/uploads/' + req.body.uid
    },
    uploadUrl: function () {
      return '/uploads/' + req.body.uid
    }
  })(req, res, next);
});
app.use(express.bodyParser());
